WiFi not working after installation

Hi all, my WiFi was working during the installation of Arch Linux, but after the installation, it's not working.

My WiFi usb is Tenda W541U 2.0,

In terminal i got this when i type "iwctl" then "adapter list":
phy0               on        Ralink Technology, CRT2070 Wireless Adap

And when i type "dmesg" I got something like below:

[ 2775.686817] rt2800usb 1-7:1.0: Direct firmware load for rt2870.bin failed with error -2
[ 2775.686820] ieee80211 phy0: rt2x00lib_request_firmware: Error - Failed to request Firmware
[ 2775.687197] ieee80211 phy0: rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'

I've visited the ArchLinux wiki page but not sure how to install the driver rt2870.bin? modprobe?

Could anyone assist me on this?Thanks

Re: WiFi not working after installation

You wanted to follow https://wiki.archlinux.org/title/Instal … l_packages because then you probably had installed linux-firmware…
